[Libguestfs] [libnbd PATCH 0/4] API: stats tracking

[Eric Blake]

With this, I'll be able to clean up test 3/12 in the pending
opt_set_meta_context() series to test whether filtering was done
client- or server-side.

Eric Blake (4):
  internal: Track traffic stats
  generator: Add RUInt64 for 64-bit counters without error
  api: Add new nbd_stats_*() statistics counters
  tests: Add language binding tests for stats reception
